One of the most impressive videos i've seen on the subject of evolution. This is the first time i've ever written a public comment, which is a measure of just how impressed i am. As a retired lecturer, i consider that i can recognise true professionalism when i see it. One thought - would a map have been useful when talking about pop. movements? Or would that have taken away too much focus from what was being said?
@alexandermukai7724

A map would have given the impression that those population movements had been determined with some certainty. What I understood form this lecture was that the genetic data indicates mixing and dispersal of genes in and to certain regions, but, I would conjecture, how those genes got dispersed is, as yet, uncertain.

I was watching another video about Denisovans that was so muddled and making way out claims of 10,000 rpm tools used to make a piece of jewelry found in a Denisovan cave. I wonder why only one tiny bone and 2 teeth have been found in 30 years so far. If anyone knows, please post something. I suppose if they buried their dead it would have been in a different cave or not in a cave at all, or perhaps they didn't believe in rituals around death too. I wonder with the genome now so well preserved if it gives information as to what they looked like in profile and average height and facial features etc.

...Answer: As I understand this video, Man originated in Africa and spread across Europe and into Asia, evolving their own antibodies against whatever diseases they found in those places, through natural selection. Then later, an evolved type of Man; our Human Ancestors came out of Africa as a wave, mating with the indigenous populations as they went. Until relatively recently, our Human Ancestors did not successfully advance into those areas of Australia/New Guinea, and that's why the Denisovan population is so prevalent there. Have I got that right?

( Cliff Notes Synopsis on the Second Wave Re-introduction of the Vermin Gene ) ------------------------------------------------------------------------------------------------------------------------------------------- the tempered tool maker strains likely emerged from some early offshoot from the early australopithecines.. homorudolfensis remnats becoming homoerectus.... i think that was when the initial assumed tech overshoot shit started hitting the fan in africa was the end of homorudolfensis....and homohabilous stuck it out until the survivors there left africa as homoheidelbergensis...and neandrathal and denisovan was likely in some recombination with homoerectus outside africa.... but over all, between tchadensis and homonaleti is a mega-time span that shows a continuous "littering" from the canopies resulting in variable survival spans of different attempts at bipedal evolution... so palioptroteomics, could work on recovering the DNA of peking man, or as far back as that strain of homoerectus in asia, and also homoheidelbergensis.. Neanderthal was stabilized in europe for 60,000 years...those were large brained hominids as advanced as any of those times...their weapons were designed to take quarry, not other hominids.. same with their Denisovan cousins in asia...there, stable back to Peking Man also.. their relations, east nile Homoheidelbergensis, had evolved weapons designed to also be used against hominins...and i am confident in stating there was likely a reason for that.. my point is, there were no anthropocenic prey species die offs in eurasia until the second wave.. facebook.com/rulgert.ghostalker/

Help me understand. It is said that we share 98.8% of the same DNA as a Chimpanzee but only 1-4% with Neanderthal and Denisovans. I am sure people are using different formulas to explain our relationship with these relatives because it is obvious that we are much closer related to Neanderthal and Denisovans than a chimpanzee. So my question is: What is the actual percentage total that we share with these relatives? Correct me if I am wrong but I am sure that we share more than 4% of our DNA with a tomato but I am not going to mate with one and then have tomato DNA in the human Genome.

Question, I herd a hypothesis that the people that make Australian Aboriginals, native's of Papua New Guinea , and other people's of Oceania came form a sub-set of people that came out of Africa before the wave of people that would latter become Asian's, Europeans, and so on. If that is the case, I have my own idea that is just hypothesize. What may account for the different Denisovan percentage between Australian Aboriginals, native's of Papua New Guinea , and other people's of Oceania than that of the people of East Asia is that the Denisovan's died out between the two waves of modern Humans and the Denisovan percentage in East Asians were watered down by the second wave of humans that came from from Africa.

This interbreeding has been going on since the dawn of life and the end result is every living thing on earth today. I believe we are all a combination of every living thing on earth.

Ken MacMillan It is my understanding that they can not reconstruct what a species looked like based on looking at the dna. We need to look at a living species with and without a specific trait to see the difference and tell what it does. We would need to study people that had specific denosovan dna traits to see what each does. We only inherited some of the dna so it would only tell us what they looked like if they passed on dna that affected looks. Over time we will discover what the inherited dna does to modern humans and might be able to determine what they looked like. Finding a full skeleton would also go a long way to increase knowledge. Not an expert but this is what I think I have heard from several dozen videos on the subject.

Judging by the size of the teeth they were quite large. If a large population of hominids - i.e. Denisovans (add floresensis, the Penguins find, Chinese unexplained fossils and the 2 seperate, different Red DeerCave people finds plus Homo Naledi to this as well) that lived so close until this time (also taking into account the extremely scant amount of human fossil evidence today's theories and models are based upon) can go undetected by archaeological science up until today, regarding no fossil record, one wonders what else lies in store ahead in this very interesting field of research. I am sure that there is so much more to uncover and discover and we have but merely scratched thus race when finding out what really transpired with our current models.
